LPG Inert IG-541
The natural extinguishing
agent
• Natural gas present in the atmosphere
• Design in compliance with ISO 14520, NFPA 2001
and CEA 4008
• Suitable for occupied areas
• Electrically non-conductive
• No residue to clean up after the discharge
• More economical and less storage space
• Zero Ozone Depletion Potential
• No greenhouse effect
• No decomposition products
LPG INERT® IG-541 is a mixture with 52% NITROGEN
(IG-100), 40% ARGON (IG-01) and with 8% CARBON
DIOXIDE (CO2). It is an inert gas, non-conductive,
colourless, odourless and Ńavourless. It is non
corrosive and may be used at normal temperatures with such materials as nickel, steel, stainless
steel, copper, brass, bronze and plastics.
Perfect
dielectric and appropriate for the
protection of all the electric and electronic
materials.
Discharge is through valves fully developed by
LPG approved by the most renowned independent
organizations. They offer a great Ńexible adaptability
for all actuation and release systems currently
used in the market, even allowing combinations
of several of them.
The design of the system protects against
accidental actuation due to any small leak. They
also allow checking and maintenance of all critical
elements contained in a fixed extinguishing system,
at the time of commissioning and later for system
preventive maintenance, thus preventing the
risk of accidental discharge. As a general rule,
extinguishing concentration is achieved when
oxygen contents in the air is reduced from its
usual level of 20,9% to values lower than 15%
depending on the combustible products.

LPG INERT® IG-541 is stored in high-pressure cylinders
in the form of compressed gas, thus space required
for such cylinder storage depends on pressure and
capacity.
IG-541
fire
extinguishing
systems
are
designed
for
a
cylinder
filling
pressure
of 200/300 bar. LPG uses cylinders of
80 lt. and 140 lt. capacity, thereby, optimazing in
space and cost.
LPG INERT® IG-541 systems can be modular or
centralized (single or double row). The system with
manual or automatic release includes ʌ (PI) certified
bottles, equipped with a pressure gauge valves.
LPG INERT® IG-541 is safe for use in occupied areas
and excellent visibility is maintained during discharge.
Ideal for the protection of archives, museums,
libraries and any other hazard including valuable
or unique property. Likewise it is suitable for the
protection of computer rooms, telephone exchange
equipment and any other electrical installation that
may present a fire hazard.
